Answer:
d = 9.5× 10⁻⁴ Kg/cm³
Explanation:
Given data:
Length of cube = 1.02 cm
Mass of cube = 0.001012 Kg
Density of cube = ?
Solution:
The length , height and width of cube is always same. Thus the volume of cube is,
Volume = length × height× width
Volume = 1.02 cm × 1.02 cm × 1.02 cm
Volume = 1.06 cm³
Density of cube:
d = 0.001012 Kg /1.06 cm³
d = 9.5× 10⁻⁴ Kg/cm³
Answer:
1.35 m
Explanation:
We can solve this problem by using the <em>freezing point depression formula</em>:
Where:
- ΔT is the temperature difference between the freezing point of the pure solvent (water) and the solution. In this case it is (<em>0 °C - -2.5 °C = 2.5 °C</em>).
- Kf is the cryoscopic constant, <em>for water it is 1.853 °C*kg/mol.</em>
- i is the van't Hoff factor, <em>as sugar does not dissociate in water, it has a value of 1</em>.
We <u>input the data</u>:
- 2.5 °C = 1.853 °C*kg/mol * m * 1
And <u>solve for m</u>:
Question 1.
The above statement would resultant as <span>The 1500 kg of water will reach a higher temperature.
Question 2
</span><span>A system in which matter and energy are not exchanged with the surroundings is a best statement for an isolated system.</span><span>
